DOJ files suit against California laws restricting immigration enforcement, prohibiting information-sharing, and requiring detention facility inspections as "sanctuary" laws

  1. Date Announced

    March 6, 2018

The laws being challenged are SB 54 ("California Values Act"), AB 450 ("Immigrant Worker Protection Act") and AB 103 (re inspection of detention facilities). These laws pertain to information-sharing with federal authorities, inspection of immigration detention facilities, and workplace protections. [ID #308]
